CAR-BUFFER.

SPECIFICATION forming part of Letters Patent No. 604,451, dated May 24,1898.

Application filed Septernber 21, 1897. Serial No, 652,442. (No model.)

To all whont it may concern:

Be it known that I, HERMAN F. BALL, a citizen of the UnitedStates,residin g at Cleveland,

in the county of Cuyahoga and State of Ohio,

have invented certain new and useful Improvements in Oar-Buffers; and Ihereby declare the following to be a full, clear, and exact descriptionof thesame, reference being had to the accompanying drawings,in whichFigure 1 is a plan view of a car-buffer embodying my invention. Fig. 2is a longitudinal central section thereof on the line 2 2, Fig. 1. Fig.3 is a detached plan view of the base-section or spring-box. Fig. 4c isan inverted plan View of the cup friction-plate, and Fig. 5 is adetached plan view of the slip-ring which secures the cup friction-plateto the base-section or springbox.

Like symbols refer to like parts wherever they occur.

My invention relates to the construction of that class of car-bufferswherein are combined a base-section or spring-box, a telescoping cupfriction plate, and interposed buffersprings, and has for its Object theprovision of strong, simple, and efficient means for combining thetelescoping sections and preventing the rotary movement of one sectionupon the other.

To this end the invention, generally stated, embraces the combination,with a flanged spring-box or base-section, of a flanged telescoping cupfriction-plate which incloses the flanged spring-box, interposedbuffer-springs, and a removable collar or slip-ring which looselyencircles the spring-box or base-section and is detachably attached tothe flange of the cup friction-plate for confining the friction-plate tothe base-section.

I will now proceed to describe my invention more fully, so that othersskilled in the art to which it appertains may apply the same.

In the drawings, A indicates a base-section or spring-box, preferably ofcylindrical shape and provided with a base-flange a, by means of whichit may be bolted to the car in the usual manner. At the opposite or openend the base-section or spring-box A is provided with anoutwardly-projecting flange 1, having a series of recesses 2, whichserve a double purpose-first, for the passage of corresponding lugs on aslip-ring or collar D, and, second, for the engagement of ribs, lugs, 0roflsets'o on the interior of the cup frictionplate of the buifer. On theinterior and at the bottom of base-section or spring-box A a lug orprojection 3 may be provided for holding and centering the lighter andlonger buifer-spring c, which supports the friction- .plate under theinitial impact in bufling.

B indicates the cup friction-plate, which may be provided on itsinterior with a centering-lug 5 for the light center spring 0. Thegreatest inner diameter of this cup friction-plate B will be such as topermit it to pass freely over the outwardly -projecting flange 1 of thebase-section A, and it will be provided on its interior with one or more(preferably a plurality of) ribs or lugs 6, adapted to engage in therecesses 2 of the flange l, and thus prevent the rotation of the cupfriction-plate B on the base-section A, as well as to guide itstelescoping motion thereon. These ribs 6 also materially strengthen thecup friction-plate B. At its free edge the friction-plate B is providedwith outwardlyprojecting perforated lugs or ears 7 by means of which itis bolted to the collar or slip-ring D.

D indicates adetachable collar or slip-ring ,Whose least inner diameteris slightly greater than the exterior diameter of the base-section orspring-box A, so that it' may slide freely thereon, said slip-ringhaving a series of recesses or notches 8 of such size and so locatedthat they will register with the projections formed by the recesses 2 offlange 1 and permit the slip-ring D to pass over the flange 1 'When theslip-ring D is in a given position.

The slip-ring D is also provided with perforated lugs or ears 9 for thepassage of the bolts- 10, whereby the slip-ring D, after having beenpassed over flange 1, may be bolted to the flange 7 of cupfriction-plate B. The perforated ears 9 are so placed with relation tothe recesses S and the projections formed thereby that when theslip-ring D is bolted to "the cup friction-plate B the projections offlange 1 will oppose the inward projections on the slip-ring D, and thelatter being unable to rotate by reason of its connection tofriction-plate B and the lugs or ribs 6 therein, which engage inrecesses 2, the slip-ring D Will hold the friction-plate B securely tothe base-section A.

0 indicates the main buffer-sprin g.

The construction of the devices being of substantially the characterhereinbefore pointed out they may be combined (the buffer set up) asfollows: The collar or slip-ring D Will be passed over the flange 1 ofbase-section or spring-box A by causing the respective lugs orprojections of one to register with the notches or recesses in theother,after which the springs G 0 will be inserted in the base-sectionor spring-box A. The cup friction-plate B will then be applied, the ribs6 thereof entering recesses 2 in flange 1 of the base-section A, and theslip-ring D, having first been rotated sufflciently to bring theinwardlyprojecting lugs beneath the outwardly-projecting lugs of flange1, is finally bolted to the flange or lugs 7 of the cup friction-plate Bby the bolts 10, after which the base-section or spring-box A may bebolted to a car in the usual manner.

Having thus described my invention, What I claim, and desire to secureby Letters Patent, is

'1. In a car-buffer, the combination of a flanged spring-box orbase-section, a flanged cup friction-plate which incloses and telescopesWith the spring-box or base-section, interposed buffer-sprin gs, and aremovable collar or slip-ring which encircles the flanged spring-box orbase-section and is detachably connected With the flanged cupfriction-plate,

substantially as and for the purposes specified.

2. In a car-buffer, the combination of a flanged spring-box orbase-section, a flanged cup friction-plate, interposed buffer-spring, aremovable slip-ring which encircles the base-section 0r spring-box andis detachably attached to the cup friction-plate, and means forpreventing the rotation of the cup friction-plate on the base-section orspring-box, substantially as and for the purposes specified.

3. In a car-buffer, the combination of abasesection or spring-box havinga notched flange, a flanged cup friction-plate having one or more innerribs which engage the notched flange of the base-section, interposedbufferspring, and a slip-ring, substantially as and for the purposesspecified.

4. In a car-buffer, the combination with a base-section or spring-boxhaving a notched flange, of a flanged cup friction-plate having one ormore ribs on its interior which engage the notches ot' the flange of thespring-box, interposed buffer-spring, and a notched slipring,substantially as and for the purposes specified.

In testimony whereof I aflix my signature, in presence of two witnesses,this 18th day of September, 1897.

HERMAN F. BALL.
